For your Cougar 5th wheel trailer with a Lippert 1621 pin box rated at 15-1/2K, I recommend the Sidewinder 5th Wheel Pin Box 16K # RP34FR. This Sidewinder pin box is the confirmed replacement for a Lippert 1621.

The Sidewinder has a 16K pound weight capacity and will provide an extra 22 inches of clearance by moving the pivot point back under the trailer.

You will also need a traditional 5th wheel hitch installed in your 2010 Ford F-150. I recommend installing the hitch with the Quick-Install Bed Rails, # RP50081-58.

I also recommend the Hopkins 5th Wheel/Gooseneck 90-Degree Wiring Harness, # 41157. Adding this wring harness in the bed of you truck will allow for an easier connection between your truck and trailer. Harness plugs into existing OEM wiring. No cutting or splicing of wires will be needed for installation.

You may also need an adapter wedge that is sold separately depending on the model of your current 5th wheel hitch. The Sidewinder does include a wedge, but it will not fit all models of 5th wheel hitch.

Note: Do not use the Sidewinder with any of the following:
Curt Q Series 5th-wheel trailer hitches
PullRite SuperGlide 5th-wheel trailer hitch
Reese Trail Boss 5th-wheel trailer hitch
B&W Companion 5th-wheel trailer hitches that mount in the Turnoverball gooseneck hole
Colibert 208BW 5th-wheel trailer hitch
Hi-Rise gooseneck-to-5th-wheel adapter by Draw-Tite, Hidden Hitch, Bulldog and Reese
Any other gooseneck-to-5th-wheel adapter.
